Noticing and absorbing are not the same things. Here's a simple (relevant and connected) experiment. Go play Reach and mentally note the content of the text streams. They appear on the lower left of the screen.
Now play something super frighteningly abrupt, like SWAT or Snipers. Do the same thing.
Now think about your reticle - and what your eyes did, however briefly, while absorbing that information.
As to the "what's the point" question - there are dozens of points, all related to getting information and advice to all kinds of players. It's not going to be perfect for everyone, nothing is, but I suggest trying it - and again, I am fairly confident about this in real life.
Truly in that example, the difference for
me would be in how I relate to text in a game type that focuses on
team play (default Reach), vs
individual play (SWAT and Snipes) rather than a difference in type of action.
Of course noticing and absorbing are two different things... and I get moving the information in so far as when it's in the middle, more people will be able to catch what is delivered than when it was lower left. I'm sure it's part of making the game more accessible for people. The problem for
me now is, I cannot escape seeing it where before I could choose to see it. Should I choose, I could check on who killed whom without seeing head shot, assist, medals, etc. I could absorb the important stuff and ignore the rest.
There is more information given than I personally value. The only information I value out of the text stream is who killed whom. Everything else is fluff.
For me... the rest adds no value to my game play experience DURING the game, and being notified of medals, assists, head shots, etc.; only adds value AFTER the game.
I'm not saying it's a particular problem (after all, I play other games with MUCH more going on than H4's display)... and I block that stuff out... nor am I worried about it exactly... just saying I'm in the camp of "less is more", and I play with a friends list full of people who feel the same way.
If I could choose where to place information, I'd rather it be out of the center... and could I choose the type of information, I'd rather not see things that have no bearing on the competition at hand. I want information that I value, to be accessible, but not necessarily overt.
